dmidecode is a userspace command-line utility for Linux that can parse the SMBIOS data of your computer. This utility is handy to display system information without having to reboot into the UEFI/BIOS. Details are in 'man dmidecode' for the various options; I prefer the "--t, --type TYPE" option as it also uses human readable TYPE keywords to groups and drill into the specific information needed. The inxi utility usues dmidecode (and many other utilities) and some nice formatting to deliver comprehensive system information.

After celebrating the release of Slackware 15.0, it was time to migrate LinuxGalaxy.org. Since the new OS includes a working python3 stack by default, getting my CMS and other tools up and running was much easier.
Previously, this site was using a custom compiled python3 installation with various python modules installed using pip and venv. This made it difficult to track what versions of these modules were installed using the tools I'm accustomed to. It also presented problems with reproducible builds. Using pip (and various other web-based package managers) make it difficult to maintain consistent versions of a given module across multiple machines.
To work around that issue, you either need to tell pip which versions you want installed, or build your own custom packages. Since 15.0 includes several of the most common python modules, the latter option requires significantly less effort on my part.
Other than that, the migration from 14.2 -> 15.0 is no different than it has been for any previous version. While there are a lot of new packages and systems the standard Slackware experience is no different than it was 10 years ago.

As a fan and user of the best Gnu/Linux distribution by far, I am all a-quiver with this new release. Slackware-14.2 still worked well as a desktop operating system, but after 6 years, even for an LTS, it was getting a bit crusty. Read the announcements and enjoy! Don't forget Slackware now has a live boot image if you just want to take Slackware for a test drive.

A query was posted recently on a list on how to convert date formats in the form of "month/day/year" into a more standard unambiguous "year-month-day". I dabbled in Perl a very long time ago and so thought I'd take a look. After searching the Internet and some practice, here is my stab at it. For an example csv text file, for tabular data in this case:
